Honest Infrared Sauna Comparison: Therasauna VS Sunlighten

Hi Matt, between Therasauna and Sunlighten, which do you think is the better buy? It looks like you bought a lower end Therasauna and didn't have a good experience with it. But I don't see Sunlighten mentioned on your Certified Saunas list, any reason why? Just curious since you said in another video that Sunlighten makes good saunas. Also have you been back in a higher end Therasauna? Thanks for any direction! https://youtu.be/mBfgO8oXpdE
